摘　　要：刘庄地区沙一段是该区主要的含油气层段之一,通过对工区内储层和构造特征的精细研究,解剖了沙一段的油气成藏条件及富集成藏的基本特征;探讨了工区油气聚集成藏的四种控制因素:构造发育史及构造格局控制着油气富集区的分布、II级和III级断层控制油气的运移、构造位置决定了油气富集程度、储层发育程度影响油气富集;总结了沙一段主要油气聚集成藏类型和成藏模式,即构造油气藏和构造-岩性油气藏,正向地垒构造样式运移成藏模式和断节构造样式运移成藏模式。Sha-1 member is the one of the main oil and gas bearing zone in Liuzhuang region.Based on the fine research on features of reservoir and structural,the basic conditions and accumulation characteristics of oil and gas reservoir formation in this area are analyzed.There are four kinds of controlling factors of the oil-gas enrichment:tectonic framework development history and the distribution of oil-gas bearing area are controlled by tectonic framework,the hydrocarbon migration are dominated by gradeⅡ&Ⅲ faults,the enrichment degree of oil and gas accumulation are determined by the location of tectonic,and hydrocarbon enrichment are influenced by the degree of reservoir development.Research findings show that structural and structural-lithology oil-gas reservoirs,forward horst tectonic style migration and segmental tectonic style migration patterns reservoir formation,mainly developed in the sha-1 member.
